Within the sex-shared nervous system, we found that
mab-3 is not only male-specifically expressed in the ADF neuron, as previously reported (Yi et al., 2000), but also in additional head neurons, including the embryonically generated SMD head motor neurons. We found that like the male-specific, neuronal expression of
lin-29a, male-specific neuronal expression of
mab-3 is precisely timed to commence at the L4 stage.
